CVE-2026-120533 · Severity: medium · CVSS 6.4 · Published 2026-11-05

Redux Framework is a WordPress plugin used to build customizable theme settings panels. An authenticated attacker with subscriber-level access can inject malicious JavaScript into theme option fields, which executes when other users view pages that output those settings. This requires the theme to use specific Redux field types that output CSS, allowing attackers to steal credentials, deface content, or compromise site visitors.

## How to fix

## Technical details

Stored cross-site scripting vulnerability in the theme_opts parameter due to insufficient input sanitization and output escaping. Authenticated attackers (subscriber-level and above) can inject arbitrary web scripts that persist and execute in pages. Exploitation requires the theme to have registered a Redux field of a CSS-emitting type (link_color, border, typography) with an output CSS selector; spinner, slider, color, and date field types have per-type validation that blocks entity-encoded payloads. Fixed in version 4.5.18.
